15. Which of the following statements is best
supported by the information in the graph?
O A. Pebbles are able to be moved at slower
stream velocities than silt particles.
O B. Streams are only able to move particles
less than 1 cm in diameter, and all other particle
sizes can only be moved in rivers.
O C. Particle diameter controls stream velocity
across all scales.
O D. Small increases in stream velocity can lead
to many changes in particle size at slower
velocities, but changes in larger particle sizes
require more significant changes at higher
velocities.
